Legal claims defining the scope of protection, as filed with the USPTO.
1. A PCMCIA card including a secondary device that provides functionality to a primary device when said PCMCIA device is coupled to said primary device, said primary device providing power to said PCMCIA card at a maximum current and power level, and said secondary device having operating characteristics that, at least at certain times, exceed said maximum current level, said PCMCIA card comprising: a storage battery capable of delivering power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device, whereby said PCMCIA card is configured to couple said secondary device to said storage battery on demand to provide said secondary device with power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device.
2. A PCMCIA card according to claim 1 , further comprising: a battery charging circuit, coupleable between said primary device and said storage battery; whereby said battery charging circuit is configured to recharge said storage battery.
3. A PCMCIA card according to claim 2 , wherein said secondary device comprises a device that provides wireless functionality to said primary device.
4. A PCMCIA device according to claim 3 , wherein said secondary device further comprises a device that provides cellular functionality to said primary device.
5. A PCMCIA card according to claim 1 , wherein said secondary device includes a power amplifier that has power requirements that exceed said maximum current and/or power level.
6. A PCMCIA card according to claim 5 , wherein said primary device comprises a portable computer.
7. A PCMCIA card according to claim 5 , wherein said primary device comprises a PDA.
8. A PCMCIA card as set forth in claim 5 , wherein said primary device comprises a desktop computer.
9. A PCMCIA card according to claim 1 , wherein said storage battery comprises one or more Lithium Ion batteries.
10. In a PCMCIA card including a secondary device that provides functionality to a primary device when said PCMCIA device is coupled to said primary device, said primary device providing power to said PCMCIA card at a maximum current and power level, and said secondary device having operating characteristics that, at least at certain times, exceed said maximum current level, a method of providing power to said secondary device that exceeds said maximum current level comprising the steps of: providing said PCMCIA card with a storage battery capable of delivering power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device; and coupling said secondary device to said storage battery on demand to provide said secondary device with power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device.
11. The method of claim 10 , further comprising the steps of: providing said PCMCIA device with a battery charging circuit, coupleable between said primary device and said storage battery; and recharging said storage battery using said battery charging circuit at predetermined times.
12. The method of claim 10 , wherein said storage battery is built into said PCMCIA card.
13. A system for providing functionality to a primary device when a PCMCIA device is coupled to said primary device, said primary device providing power to said PCMCIA card at a maximum current and power level, and said secondary device having operating characteristics that, at least at certain times, exceeds said maximum current level, said system comprising: a PCMCIA card; a storage battery built in to said PCMCIA card, said storage battery capable of delivering power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device; and coupling means for coupling said secondary device to said storage battery on demand, to provide said secondary device power at a current and/or power level that exceeds the maximum current and/or power level provided by said primary device.
14. The system of claim 13 , further comprising: a battery charging circuit, coupleable between said primary device and said storage battery; whereby said battery charging circuit is configured to recharge said storage battery.
15. The system according to claim 14 , wherein said secondary device comprises a device that provides wireless functionality to said primary device.
16. The system according to claim 15 , wherein said secondary device further comprises a device that provides cellular functionality to said primary device.
17. The system according to claim 13 , wherein said secondary device includes a power amplifier that has power requirements that exceed said maximum current and/or power level.
18. The system according to claim 17 , wherein said primary device comprises a portable computer.
19. The system according to claim 17 , wherein said primary device comprises a PDA.
20. The system as set forth in claim 17 , wherein said primary device comprises a desktop computer.
21. The system according to claim 13 , wherein said storage battery comprises one or more Lithium Ion batteries.
